Not good enough05/06/2016NoneSplit too easilyResponse of the brandHi David,
Thank you for taking your time to review the inner tubes. I'm sorry to hear that you have faced such issues with the quality of them. I'd suggest that you return them to your local store on your next visit to get a refund.
I will pass your concerns over the quality of these to the product manager to ensure the quality is as good as it needs to be.
